Our espresso machine has been malfunctioning since Joel and Cheryl were here (coincidence? - I think not!) so I cracked it open to have a look.
Come to find out, the water pump activation microswitch on the steam wand bypass port was being tripped by a misaligned rotary cam. So I deftly gave it The Wiggle and viola!!!....out pops this pretty Mocha in no time flat.
All's well with the Barista. Now I can resume full morning mocha production without having to stop at a drive thru, which is why I'm late to work most of the time. And other stuff.
